I think that this might cause problems in high-concurrency situations:
user a: selects max ID (23)
user b: selects max ID (23)
users a and b insert features
user a: selects max ID (25)
user b: selects max ID (25)
??

Another approach might be to select the Max Id before the insert and
select the Max Id after the insert. I don't believe the Id's get
assigned such that they will use existing gaps (from deleted features)
so the new Id should always be higher correct?
